The Ivy League school has experienced an outbreak of type B meningococcal disease. Seven students and one student visitor have been stricken by the potentially life-threatening bacterial illness since March. None of the cases has been fatal.

“It’s about a 1 in 750 chance of getting meningitis for a student here,” Dr. Thomas Clark of the U.S. Centers for Disease Control and Prevention told CBS 2’s Syma Chowdhry.

University officials say the vaccine will be made available on campus from through Dec. 12 to nearly 6,000 students. All undergraduate students will be offered the shot, as well as graduate students who live on campus.

The second dose will be administered in February.

The vaccine for this particular strain of meningitis is only licensed for use in Europe and Australia but not in the United States. The Food and Drug Administration is allowing for its limited use at Princeton.
